style(ui): apply cyberpunk neon theme across all menus

- replace color palette with Cyberpunk 2077 neon variants in lib/common.sh
- add DIM, BLINK, REV attributes and show_title ui helper
- make show_separator terminal-width-aware via tput cols
- restyle menus with ◢ numbered items and ▸_ prompt indicator
- support two-digit input aliases (01-05, 00) alongside single-digit
- update status tokens: [✓]/[✗] → [OK]/[KO], PURPLE → MAGENTA
- apply consistent ui changes to lxs.sh and tools/index.sh

lib/common.sh
